What Statement Concerning the Pathogenetic Mechanisms of Polycystic Ovarian Syndrome

question 3

Multiple Choice

What statement concerning the pathogenetic mechanisms of polycystic ovarian syndrome (POS) is true?

• A) POS causes a decrease in leptin levels; this decrease reduces the hypothalamic pulsatility of gonadotropin-releasing hormone, which reduces the number of follicles that mature.
• B) POS is a result of a disorder in the anterior pituitary that increases the follicle-stimulating hormone, which reduces the luteinizing hormone released.
• C) POS is a result of a combination of conditions that include oligo-ovulation or anovulation, elevated levels of androgens, or clinical signs of hyperandrogenism and polycystic ovaries.
• D) POS inhibits testosterone, which stimulates androgen secretion by the ovarian stroma and indirectly reduces sex hormone-binding globulin.
